IMPROVE!) MAGHINE FOR-MAKING cUT-NAILS.

. The Schedule referred to in these Iiettera Patent and making part o! the same.

Be it known that we, SJK. J ONES and GEORGE H. SNOW, of New Haven, in the county of New Haven, and State of Connecticut, have invented a new Improvement in Nail-Machine; and we do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference -marked thereon, to be a full, clear, andexact description of the same, and which said drawings constitute part of this specication, and represent, in-

,Figure 1, a topview. y

Figure 2, a'side view.

Figure 3, a` front view.

Figure 4, a longitudinal section.

Figures 5` and 6, detachedsectional views, to illustrate the construction and operation.

This invention relates to an improvement in machines for making nails from sheet-metal, the machine being designed withspecial reference to the manufacture of the nail for which Letters Patentv'vere granted to A. A. Wilcox, August 14, 1866, butis alike applicable to making nails,y or tacksof any other descrip-y tion from sheet-metal; and l y The invention consists in the arrangement of a platefeeder, in combination with two alternately-acting cutters,so. that the said feeder will, by a reciprocating movement, present the plate `to each cf the twol cutters, so that the` first nail is cut by one o`f the cut ters, the next by the second, andso on; also, in the device forheadiug the nail after it has been cut.

YTo enable others to construct and use our improvenient, we will fully describe the same,as illustrated in .the accompanying drawings.

A is the bed or frame upon which the machine is placed, the whole machine being hung on the said bed uponbearings B, so that the machine may be-turned up, for the purpose of adjusting the parts underneath y 0n the said bed-plate, in properf bearings `D,'the driving-,shaft E is arranged, so as to revolve freely therein, power being` applied theretoin any convenient or known manner. Y,

. Upon the said bed, and in prope'r guides F, are arranged two vertical4 slides G 'audG, the said slides being moved up and down by means of cams I and I, upon the' driving-shaft E, through levers H and H, the said levers being hung upon a fulcrum H?.

In each of the said slides G and G are fixed, re- (See figs. 3, 4, "and The cams which operate the said slides are arranged so that the operation of the slides is alternate, that is,

the one rising While the other descends, and vice tersa..

` '.On the bed-plate` C, and in proper relativeposition to the cutters K and K', are` arranged fixed cutters L, (see ligs. 4 and 5,) so that the vertical cutters pass down across the edge of the fixed cutters L, and the combined action of the movable and lixed cutter cuts in like manner as iu ordinary cutting-machines.

M is a slide arrangedl transversely across the ma chinein guides Ml, and operated to move the said guides by theaction yof a crank, N, on the drivingshaft, which is connected to a slide, N1, moving in guides N i, at right angles to the slide M, and the said slide N1, actingupon a bellcrank-lever N3, pivoted at N4, and in connection with a slide, N 5, so that as the crank revolves the slide M is Amoved transversely across the bed-plate, and upon thel said slide M is arranged Vthe nail-plate feeder M2, so as to move with the slide M.

Upon the plate-feeder M? are arranged guides `fm, adjusted to the width of the nail-plate.

Upon the feeder is arranged acylinder, M3, upon a shaft, M, the cylinder M3 being arranged in a spring- .bearing, as seen in iig. 4, so as to press upon the plate,

and so that, by the revolution ot' the cylinder, the plate may be forced inward, toward the cutters, and the cylinder is caused to revolve by the application of power to the shaft, as seen inllig.,1, or otherwise, it being arranged so that the cylinder, with the feed, may be moved transversely across the machine with the slide M, so as at the proper time to present the plate to each cutter.

The plate being inserted beneath the cylinder M3 is, by the revolution of the saidoylinder, forced forward `to the cutters; .and when it is presented to the cutter K, the plate is forced` under the cutter, until f arrested by a proper stop, and there remains stationary, until the descending cutter K has cut from the plate the requisite quantity of metal; then, through the'action of the Acrank N, the plate is moved across to the other cutter K, the plate fed in and cut by the cutter K', then returned to the other cutter, and so continued.

After the blank has been cut from the\nailplate, it

isnecessary to `transfer it to the heading-die. f This is done as seen in figs. 4 and 5. y Beneath each of the cutters is arranged a vertical slide, A and A, upon which is arranged a die, or holder, a, denoted infr'ed, lig. 4, and upon thesaid die a spring-catch, fl.. l

The slide Al, which carries the said die, or holder',

is operated by a cam on the driving-shaft E, through'I .a lever A2, so as to raise the said die, as from the sition in fig. 4 to that in g. 5. It is raised to the position in lig. 5 immediately bef fore the descending of the cutter, and so thatthe said die, or holder ,c acts asa stop for the plate, to arrest the plate-when it `has been fed under thecutter,'to cause the requisite quantity of metal to be cut from the plate. i y

Upon the descent of the' cutter, as seen in lig. 5, the bevelled edge ofthe cutter strikesv the head of the springicatch d, and forces it back, as denoted in ltig. 5; butas the cutter ascends, the catch. returns over the blank which has been cut, and thus grasps the blank.

Then the blank is carried down bythe' return of the slide A' to. the position denoted in lig. 4, while the Hunt heading is being performed; and upon the descent of the blank the holding-dies f and g, seen .closed in lig. 4, and operated by the cams on the driving-shaft, are opened, as denoted in red, fig. 5, and so soon as the blank has been carried down the said dies g close upon the blank, and carry it forward to the position in fig. 4, which is in position to be headed.

'.lhe operation of the heading-die is shown in fig. 6, the two dies g g grasping theblank.

The heading-die h is arranged in the slide P, operated by the cam Pl on the driving-shaft, through levers P, and when the blank is presented by the dies g g,

as seen in figs. 4 and (i, then the heading-die h is forced forward, and heads the blank. The die is then opened to discharge the nail. The operation is continued, and nails successively cut and headed, the nail-holder and heading-dies upon each side oi the kmachine operating relatively to their respective cutters.

The nail for which this machine is specially'adapted is that patented as aforesaid, and as seen'in Figure 7; but it will be readily seen by those skilled in this class of manufacture that the machine is equally adapted to the making of other descriptions of nails or tacks, and that by the arrangement of the feed, presenting the same plate to alternate cutters, the production of the machine is doubled, `because the cutters and headingdies may each operate equally as fast as in common nail-machines; consequently the two combined must operate twice as fast, and, the action being alternate, very little, if any more power is required to drive the two combined than the common single machine.

The adjustment of the parts for a di'erent size or class of nails is of such a nature that any person skilled in the construction of similar machines will readily nnderstand.

Having thus fully described our invention,

What we claim as new and useful, and desire to secure by Letters Patent, is,-

1. In combination with the' revolving cylinder M5, movablecutters K and K', and fixed cutters L and L', constructed and arranged to operate in the manner described, the transferring-die awith its spring-catch d, as and for the purpose specified.

2. The combination ofthe movable cutter K, fixed cutter L, transferring-die a, with its spring-catch d, and the holding-dies f and g, constructed and arranged so as to operate in the manner described.

i 3. In combination with the subject-matter of the secondclause of' claim, the heading-dies, operating as set forth.
